Abstract

The invention relates to a liquid crystal display device and a driving method thereof. The liquid crystal display device comprises a public voltage generator and a plurality of soft printing circuit boards; the soft printing circuit board comprises a plurality of data lines which are electrically connected with the public voltage generator; the data signals of a plurality of data lines are transmitted to the public voltage generator which adjusts the public voltage of the liquid crystal display device according to the voltage changing value when the polarity of the data signal is reversed. The liquid crystal display device can effectively improve the crosstalk interference and improve the display picture quality.

Description

technical field [0001] The invention relates to a liquid crystal display device and a driving method thereof. Background technique [0002] Liquid crystal display devices are widely used in electronic display devices such as mobile phones, televisions, and notebook computers due to their characteristics of low radiation and thin thickness. [0003] see figure 1 , is a structural schematic diagram of a prior art liquid crystal display device. The liquid crystal display device 10 includes a scanning driving circuit 11, a data driving circuit 12, a plurality of scanning lines 13 parallel to each other, a plurality of data lines 14 parallel to each other and perpendicularly intersecting with the scanning lines 13, and a plurality of data lines 14 located at the The pixel unit (not shown) at the intersection of the scan line 13 and the data line 14, wherein three adjacent RGB pixel units form a pixel (not shown). The scan driving circuit 11 is used for driving the scan lines 1...
